Vector vs Raster: Real-World Guide for Business Owners

Vector vs Raster: Real-World Guide for Business Owners

Let me tell you about a conversation I have at least once a month.

A new client, typically a seasoned entrepreneur who has been in business for 5-10 years, comes to us seeking a rebrand or a new website. I ask the standard question: “Great, can you send over your current logo in a vector format? An .AI, .EPS, or .SVG file would be perfect.”

Then comes the pause.

Nine times out of ten, they email me back a 200-pixel-wide JPG they ripped from the header of their website. When I tell them we can't use it for their new trade show banner, they're confused. “What do you mean? It looks fine on my screen. Can't you just… You know, make it bigger?”

“No. I can't just make it bigger.”

This single misunderstanding—the fundamental difference between Vector vs Raster—is the source of more wasted time, money, and frustration in the design world than any other. It’s the reason your logo looks “fuzzy” on a flyer, why your printer rejected your artwork, and why your web developer is complaining about your “massive” PNG files.

This isn't your fault. Nobody taught you this. But understanding this one concept is the most important technical lesson a business owner can learn about their own brand.

This guide aims to clarify the confusion. We'll eliminate complex jargon and use real-world examples. By the end, you'll know exactly what files to demand from your designer and exactly what file to send to your printer, web developer, or merch supplier.

Let's dig in.

The “Aha!” Moment: The Simple Analogy

Forget “pixels” and “paths” for one second. Let's use an analogy you already understand: a mosaic vs a recipe.

Raster is a Mosaic

A raster image (also called a bitmap) is a giant grid of tiny, coloured squares. Think of a mosaic made of thousands of little tiles.

• Each tile is called a pixel.
• When you stand back, your eye blends the tiles, and you see a complete picture (like a photograph).
• But what happens when you get up close or try to “make the mosaic bigger”? You don't see more detail. You just see the same tiles, only now they're huge and blocky. You see the grid.

This is resolution-dependent. Its quality is locked to its original size and the number of pixels it has. A photo from your iPhone is a raster image. A .JPG is a raster image. A .PNG is a raster image.

Vector is a Recipe

A vector image is not a picture. It's a set of mathematical instructions for drawing a picture.

Think of it like a recipe for a cake:

“Draw a perfect circle. Make it 5 inches wide. Fill it with colour #FF0000 (red).”

• You can use that same recipe to make a 5-inch cupcake or a 50-foot-wide cake for a giant.
• The instructions don't change, and the result is perfectly sharp at any size. The edges will always be clean.

This is resolution-independent. Its quality is infinite. It's just math. Your logo must be a vector image. A .AI, .EPS, or .SVG file is a vector image.

Why This Matters: The File Format Nightmare

Now you get the concept. Great.

So why does this matter for your business? These two types of images are created, saved, and used in completely different ways, with different file formats.

This is where the confusion truly begins. A designer sends you a ZIP folder after a project, and it's full of digital alphabet soup:

• logo_final.ai
• logo_final.eps
• logo_final.svg
• logo_final.jpg
• logo_final.png
• logo_final_white.png
• logo_final_300dpi.tiff

You have no idea what to use. So, you grab the one you can see a preview of (.JPG) and email that to everyone. And that's when the problems start.

Getting this right is the foundation of your brand identity. It’s why we believe a deep understanding of your logo file formats is just as important as the logo design itself.

Here's the simple breakdown:

• Vector files (.AI, .EPS, .SVG) are your MASTER FILES. These are the “recipe.” You guard these with your life. You can't open them without special software, but they are the source of all other files.
• Raster files (.JPG, .PNG) are your EXPORTED FILES. These are the “mosaics.” They are created from your vector master for daily use (like your website, a PowerPoint slide, or a social media post).

You can always create a raster file from a vector file.

You cannot (easily or cleanly) create a vector file from a raster file.

What is a Vector Image? (The Business Essential)

Let's go a little deeper. A vector image is created in “drawing” programs like Adobe Illustrator, Affinity Designer, or Inkscape.

Instead of a grid of pixels, it's made of objects:

• Paths (lines)
• Points or Nodes (the start/end of a line)
• Curves (defined by math)
• Fills (the colours inside the shapes)

Because it's all just data (“draw a line from point A to point B”), the file sizes are often tiny. More importantly, every part of it is 100% editable, forever.

Need to change your logo's brand colour? A designer opens the vector file, clicks the shape, and types in a new colour code. Done in 5 seconds.

Try doing that with a raster .JPG? You'd have to “paint bucket” the pixels, which leaves a horrible, jagged edge and never looks clean.

The Test

Can you scale your logo from the size of a postage stamp to the size of a building without it losing a single drop of quality? If yes, it's a vector. If no, it's raster.

Common Vector File Formats (The “Master” Files)

This is what you must get from your logo designer.

• .AI (Adobe Illustrator File): This is the industry-standard, native “working” file. Think of it as the master document. You need Adobe Illustrator to open and edit it, but this is the king. Your designer should always provide this.
• .EPS (Encapsulated PostScript): This is the old-school, universal “master” file. It's a bit dated, but for decades, it was the only file format that every professional printer, sign maker, and embroiderer could use. It's a fantastic, reliable format for your print vendors.
• .SVG (Scalable Vector Graphic): This is the modern standard for vector graphics on the web. It's an open format, written in XML (code), which browsers can read. Your website logo? It should be an SVG. Your website icons? All SVGs. They are tiny in file size, scale perfectly on any “Retina” or 4K screen, and can even be animated.
• .PDF (Portable Document Format): This is the chameleon. A PDF can be either a vector or raster image, or a mix of both. When you save from Adobe Illustrator, you can create a print-ready PDF that maintains all the vector data. This is often what a printer will ask for, as it packages the vector logo, text, and any raster photos all into one file.

Use Cases for Vector: Your “Go-To” List

You must use vector files for:

• Logos: This is non-negotiable. 100% of the time.
• Brand Marks & Icons: Any simple graphic elements that represent your brand.
• Typography & Text: When text is saved as “outlines” (converted to vector shapes), it ensures the font will never break or change on another computer.
• Large-Format Printing: Banners, trade show booths, billboards, vehicle wraps.
• Apparel & Merch: Screen printing (needs vector paths for colour separation) and embroidery (needs vector paths for the needle to follow).
• Signage: Anything being cut from vinyl or etched into glass.

Vector: The Pros and Cons

To make this simple, here's a cheat sheet.

What is a Raster Image? (The Daily Workhorse)

Now, for the other 90% of the images you see every day.

A raster (or bitmap) image is your mosaic. It's built in “painting” programs like Adobe Photoshop, GIMP, Procreate, or Affinity Photo. These programs are all about manipulating a fixed grid of pixels.

This is the world of photographs and complex digital art. You can't use vector “recipes” to describe the subtle blend of light and shadow in a photo of a forest. You need pixels for that. Millions of them.

The Jargon Decoder: DPI vs PPI

This is where raster files get complicated. Their quality is defined by resolution.

• PPI (Pixels Per Inch): This is for SCREENS. It measures the number of pixels packed into one inch on your monitor. For a long time, the standard was 72 PPI. Now, with “Retina” and 4K displays, this number is much higher.
  • Pro Tip: For the web, PPI is mostly an irrelevant, outdated number. What actually matters are the pixel dimensions. A 1200px wide image is 1200px wide. That's all the browser is concerned with.
• DPI (Dots Per Inch): This is for PRINT. It measures the number of physical dots of ink a printer will place in one inch of paper.
  • The Golden Rule: The minimum standard for professional-quality print is 300 DPI.
  • This is why you can't use a 72 PPI image from your website for your business card. The printer will print it, and it will look blurry and “pixelated.”

The “Resolution Trap”

“But I can just change it! I opened my 72 PPI logo in Photoshop and changed the setting to 300 DPI!”

I hear this all the time. This does not work.

All you did was tell the computer to squish the same number of pixels into a smaller space.

• Your 72 PPI, 8-inch wide image (576 pixels total)
• …becomes a 300 DPI, 1.9-inch wide image (still 576 pixels total).

You didn't add quality; you just reduced the image size.

To truly “make it bigger,” the computer must guess which pixels to add to fill the gaps. This “resampling” is what makes the image look blurry and horrible. You cannot create quality out of thin air.

Common Raster File Formats (The “Daily Use” Files)

You use these every single day.

• .JPG / .JPEG (Joint Photographic Experts Group): This is the king of photos. It uses “lossy” compression, which means it discards tiny bits of data (that your eye can't really perceive) to significantly reduce the file size. This is PERFECT for photos on your website. It is terrible for logos (it creates fuzzy “artefacts” around edges) and anything that requires transparency.
• .PNG (Portable Network Graphics): This is the hero of the web. It uses “lossless” compression (no quality loss) and, most importantly, it supports transparency. Do you want your logo on a transparent background to use on your website? You need a .PNG. The trade-off? File sizes are significantly larger than those of JPGs.
• .GIF (Graphics Interchange Format): Old-school. These days, it's only used for one thing: simple, short, looping animations (memes). It has a very limited colour palette.
• .TIFF (Tagged Image File Format): The heavyweight champion. This is a massive, lossless (or uncompressed) file. It's the standard for professional photographers to save their master photos for high-end printing. You'd send a .TIFF to a magazine, but you'd never put one on your website (it would take forever to load).
• .WebP (Google's “Web Picture” Format): The new kid. This is a modern format designed to replace both JPG and PNG. It has excellent compression (like JPG) and supports transparency (like PNG). It's fantastic for site speed, but not all older browsers support it.
• .PSD (Photoshop Document): This is the native “working” file from Adobe Photoshop. It saves all your layers and edits. It's a “master” file, but it's a raster master.

Use Cases for Raster: Your “Go-To” List

You should use raster files for:

• All Photography: For your website, blog posts, social media, and print materials.
• Detailed Digital Art: Complex illustrations or digital paintings.
• Social Media Graphics: A Facebook ad or Instagram post that combines photos, text, and other elements is almost always exported as a .JPG or .PNG.
• Website Graphics: Your “hero” image, product shots, etc.

Raster: The Pros and Cons

Here's the cheat sheet for raster.

Vector vs Raster Head-to-Head

This is what it all boils down to. Here is the ultimate reference table. Print this. Put it on your wall.

“My Designer Gave Me a JPG Logo. Am I Screwed?” (The Triage Guide)

First: deep breath. This is fixable. It just might cost you.

If you paid someone $50 on a gig website, and they sent you a single JPG file as your “final logo,” you did not receive a logo. You received a low-quality picture of one.

Here is your 3-step triage plan.

Step 1: Check Your Files… Again

Go back to the very first ZIP folder your designer ever sent you. Sift through every folder. Look for ANY file ending in .AI, .EPS, or .SVG. Even if you can't open it, that's the file you need. Save it. Back it up. You're safe.

Step 2: Ask Your Designer (Politely but Firmly)

If you can't find it, email your original designer immediately. Use this exact script:

“Hi [Designer's Name],

I'm having some files prepared for a [printer/web developer] and they've requested our master logo files.

Could you please send me the original vector files for our logo? I'm looking for the .AI (Adobe Illustrator) or .EPS files.

Thanks so much,”

A true professional will have these on hand and send them right over. A hack or amateur will make excuses, claim they “lost the file,” or admit they created it in Photoshop.

Step 3: If You're Stuck… You Have Two Options

If the designer is gone or admits it was never vectorised, you're stuck with a raster image.

1. The 80% Solution: “Live Trace”
   A program like Adobe Illustrator has a tool called “Image Trace” (or “Live Trace”). It “looks” at your raster image and guesses where the paths and points should be.
   • For very simple, one-colour, blocky logos? It can do a decent job.
   • For anything with fine text, gradients, or complex curves? It will be a disaster. The curves will be uneven, the text will be distorted, and the lines won't be straight. It's a quick, dirty fix that a professional printer will spot a mile away.
2. The 100% Solution: A Professional Redraw
   This is the only real answer. You hire a professional designer or agency (like us) to take your .JPG and meticulously recreate your logo by hand in Adobe Illustrator. They will manually trace the paths, find the exact (or closest) font, and build you the true vector master file you should have had all along.
   Yes, this costs money. You are essentially paying for your logo twice. But this one-time expense saves your brand. It gives you the “master recipe” you need to operate your business professionally for the next 10+ years. We do this for dozens of new clients every year who are “liberating” their brand from bad, old raster files.

Vector vs Raster in the Real World: A Practical Guide

Okay, enough theory. Let's put this into practice. Here are your rules of engagement for every common business scenario.

On Your Website

• Your Logo: Use an .SVG (Vector). It will be tiny in file size (great for Google page speed) and will look perfectly, razor-sharp on everything, from a cheap Android phone to a 5K “Retina” display. If you must use raster, use a .PNG (for the transparent background).
• Your Icons: (e.g., the “phone” icon, “email” icon, “hamburger” menu). ALWAYS .SVG (Vector). For the same reasons: tiny file, perfect scaling.
• Hero Images / Blog Photos: Use a .JPG or .WebP (Raster). These are photographs. Compress them (using a tool like TinyPNG/TinyJPG) to find the right balance between quality and file size.
• Graphics with Transparency: (e.g., a product shot with the background removed). Use .PNG or .WebP (Raster). JPG does not support transparency.

For Your Printer (Business Cards, Flyers, Banners)

• The Golden Rules: 300 DPI minimum for all raster images. CMYK colour mode (not RGB).
• Your Logo & All Text: This must be Vector.
• Any Photos: These must be 300 DPI Raster (.TIFF) or maximum-quality JPEG.
• The Final File: Your designer will likely combine these elements (vector logo, vector text, 300 DPI raster photos) into a single, print-ready PDF (Vector-based). This is what you send to the print shop. If they ask for the “packaged” or “native” files, they are asking for the .AI file and all the linked images.

For Merchandise (T-shirts, Mugs, etc.)

• Screen Printing: (The most common, high-quality t-shirt method). Requires Vector (.AI or .EPS). The printer has to separate each colour of your logo onto its own “screen” to print the ink. They can only do this with clean vector paths.
• Embroidery: (For hats, polo shirts). Requires Vector (.AI or .EPS). The embroidery machine's needle literally follows the vector path you provide. A fuzzy raster image will result in a messy, ugly stitch.
• Digital Printing (DTG – Direct-to-Garment): This is more like an inkjet printer for fabric. It can use a very high-resolution 300 DPI Raster .PNG (with a transparent background). But even then, vector is always safer and cleaner.

The Final Word: Your One Takeaway

As a business owner, you don't need to know how to use Adobe Illustrator. You don't need to understand “Bézier curves” or “lossy compression algorithms.

You just need to be an informed client.

Here is your one, single takeaway from this entire guide:

When your logo design is complete, you MUST receive the master vector files (.AI and .EPS) from your designer.

These are your brand's most valuable assets. Back them up like you back up your financial records.

From those master files, you (or any designer) can export any other file you will ever need:

• A .JPG for your PowerPoint.
• A .PNG for your website.
• A .PDF for your printer.

Vector is the source. Raster is the output.

If you understand that, you're already ahead of 90% of your competition.

Is Your Logo Trapped in a Raster Prison?

If you've read this far and you're having that sinking feeling—realising all you have is a 15-year-old .JPG of your logo—it's time to fix it.

A brand is built on consistency. It's impossible to be consistent when your logo looks sharp on your website, blurry on a flyer, and pixelated on a t-shirt.

A proper logo design process, like the one we've refined over decades, starts with vector and ends with you, the client, getting a comprehensive file package with everything you'll ever need. You're never held hostage.

If you're ready to make a lasting change, we can help you either redesign your existing logo or create a new one from scratch.
